An optical technology already widely used in ophthalmology and other medical fields holds potential to reveal how blood flows in the brain during stroke, providing information that could someday guide new treatments and reduce ...

Imagine you need to have an almost exact copy of an object. Now imagine that you can just pull your smartphone out of your pocket, take a snapshot with its integrated 3-D imager, send it to your 3-D printer, and within minutes ...

Researchers at the National Institute of Standards and Technology have demonstrated a laser-based imaging system that creates high-definition 3D maps of surfaces from as far away as 10.5 meters. The method may be useful in ...

High power laser sources at exotic wavelengths may be a step closer as researchers in China report a fibre optic parametric oscillator with record breaking efficiency. The research team believe this could lead to new light ...

Optical coherence tomography (OCT) is a popular imaging modality for obtaining three-dimensional, micrometer-resolution pictures of structures that lie beneath the surface of, for example, the human eye or silicon wafers ...

Researchers at EPFL's Computer Graphics and Geometry Laboratory found a way to control "caustics", the patterns that appear when light hits a water surface or any transparent material. Thanks to an elaborate algorithm, they ...

In the operating room, surgeons can see inside the human body in real time using advanced imaging techniques, but primary care physicians, the people who are on the front lines of diagnosing illnesses, haven't commonly had ...

(Phys.org)—Scientists working at SLAC's Linac Coherent Light Source have captured the first single-shot X-ray microscope image of a magnetic nanostructure and shown that it can be done without damaging the material.

(Phys.org) -- In the first successful experiment of its type at SLAC's Linac Coherent Light Source, scientists used terahertz frequencies of light to change the magnetic state of a sample and then measured those changes with ...

While SLAC's Linac Coherent Light Source was designed to push the limits as a high-energy X-ray laser, users' requests have led staff at the facility to successfully step it back to a lower minimum energy for some experiments.
